We ran a 3D simulation with two parallel magnets (shown in green). The image below shows a single slide of the simulation space in the XZ-plane. The magnets extend farther into and out of the image (in the Y dimension that is not shown). We were hoping to get a near uniform field somewhere in between the magnets.
We considered two theoretical magnetic fields for particle motion (uniform field and field generated by an infinite current carrying wire). We tested the motion of various particles (electron, proton, positron, etc.) though these two categories of magnetic field. However, the simulation with two parallel nanomagnets shows how it is hard to get large areas of uniform magnetic field in the real world (no infinite planes). We did not perform any simulations, but it would be similarly difficult to get a magnetic field to match the examples we tested with an infinite current carrying wire.
